Often, the pessimist in us may begin to believe that there is simply no such thing as "good" people. However, that is simply false.
Let me begin by talking about human nature.
One fact of human nature is that we are all born skeptic. Humans are born to question, and the kids whose questions are not silenced go on to become curious and problem solvers such as scientist or doctors. (Or rather, those whose curiosity is encouraged by their environment, continue on to find more answers for their fellow man.)
In addition to our natural skepticism, we are born kind.
Science says that children learn violence and aggression.
Actions which intentionally invoke or allow pain in others are learned,
not inherited.
Children who learn through questing,
as well as rewarding of good deeds,
are natures intended human.
Even though a person may grow up being taught a 'bad' way of life, they still will conceive a "blank canvas" of a child. In other words, though the new born was birthed by someone who did not value kindness. That new child will inherently value actions made from a place of peace until said child is taught against their inherited beliefs.
Now is a great time to acknowledge that yes, some people are purely out to hurt others. However, this does not represent the majority. Let alone the 'intent vs. effect' of people's actions. Honestly, most of the pain people experience is due to misunderstandings. Humans are incredibly talented in providing for those they love and those who need help.
Love is a chemical reaction of survival, to stay near to those who keep us safe. Love is the birth right of every child ever born, this is proof that kindness is in our best interest.
I think, not only optimists see humans as good, realists also see humans for what they are: pure forces of good in both intention and practice.
